In the complex world of rubber formulation, some chemicals are specialists, while others are essential generalists. Accelerator MBTS (also known as DM) belongs firmly to the latter category. It is the reliable “workhorse” of the industry—a versatile accelerator that balances cost, safety, and performance.
For manufacturers producing everything from general mechanical goods to footwear and tires, Qingdao Chengda Huili Import and Export Co., Ltd. offers premium-grade MBTS (DM) designed to stabilize your production quality.
What is Accelerator MBTS (DM)?
Dibenzothiazole Disulfide, marketed as MBTS or DM, is a thiazole-class accelerator. It acts as a primary accelerator for sulfur-cured elastomers or as a retarder in polychloroprene (CR) rubber.
Unlike faster but “scorchier” accelerators, MBTS is valued for its moderate curing speed and excellent processing safety profile.
The Technical Advantage: Stability and Control
MBTS (DM) is frequently chosen over other accelerators when a “flat curing” effect is required. Its unique properties allow for a wider processing window.
- Flat Curing Curve: MBTS provides a long, flat cure. This means the rubber can remain at curing temperatures for extended periods without over-curing or reverting. This is critical for thick rubber articles where heat transfer is slow and uneven.
- Synergistic Power: One of MBTS’s greatest strengths is its ability to partner with others. It is often used in combination with basic accelerators (like DPG) or ultra-accelerators (like Thiurams or Dithiocarbamates) to active the cure while maintaining safety.
- Scorch Protection: While not as delayed as sulfenamides (like CBS or TBBS), MBTS offers significantly better scorch safety than MBT (M), making it easier to handle during mixing and calendering.
Core Applications
Due to its general-purpose nature, our MBTS (DM) is utilized across a vast array of sectors:
- General Mechanical Goods: Ideal for molded products where consistent physical properties are needed without the high cost of specialty accelerators.
- Footwear: Widely used in shoe soles and heels because it does not stain and allows for easy color matching in non-black compounds.
- Tires: Used as a secondary accelerator in tire compounds to fine-tune the cure rate and improve aging resistance.
- Wire & Cable: Its moderate activity makes it suitable for insulation jackets that require stable electrical properties.
The Qingdao Chengda Huili Standard
At Qingdao Chengda Huili Import and Export Co., Ltd., we recognize that “general purpose” should never mean “average quality.”
- High Purity: Our MBTS (DM) is manufactured to strict purity standards (high melting point, low ash), ensuring it disperses easily in your compound without creating “hot spots” or defects.
- Particle Size Control: We supply MBTS in optimized powder or oil-coated forms to minimize dust and ensure rapid dispersion during the mixing cycle.
- Global Logistics: We are experts in chemical export. From proper packaging to compliant documentation, we ensure your supply chain remains uninterrupted.
Optimize Your Formulation Today
Whether you are looking for a standalone accelerator for simple molded goods or a modifier for a complex tire compound, MBTS (DM) is a chemical you likely need in your inventory.
